2013 - Left nav flyouts don't show for some users

Question

Quick and hopefully easy question: On a 2013 site I have flyouts configured for the left-hand nav menu. For some new users I just added, the code I changed in the masterpage to produce the flyouts (the static and dynamic variables in the menu container) isn't running when they view the site. I gave them full permissions and made sure they weren't restricted in any way from any library (specifically the style library) but the flyouts still will not apply. They simply see the menu laid out normally as if the masterpage were unmodified. The behavior is consistent across browsers and computers. Is something blocking it at runtime? There are very few changes made to this site which is a "Document Center" template.

Edit: As requested, here is the code. It's pretty straight-forward, just changing the static and dynamic display levels.

<!--SPM:<SharePoint:AspMenu
id="V4QuickLaunchMenu"
runat="server"
EnableViewState="false" 
DataSourceId="QuickLaunchSiteMap"
UseSimpleRendering="true"
Orientation="Vertical"
StaticDisplayLevels="1"
AdjustForShowStartingNode="true"
MaximumDynamicDisplayLevels="1"
SkipLinkText=""
/>-->

Originally found the method here. Though I never managed to get the menu width to work like that guy did...

Answer 1

After editing the master you did the check in publishing the major version?

Answer 2

Can you post that modified code in your master page? I faced that problem in my last project and it was due to screen resolution for some users and browser zoom
